02 / CALCULATION METHOD
How the calculation works.
/ 02
Determine concentration
Divide total peptide mass by total liquid volume.
TOTAL MCG ÷ ML = MCG/ML
/ 03
Determine aliquot volume
Divide the target aliquot mass by calculated concentration.
TARGET MCG ÷ MCG/ML = ML
03 / REFERENCE TABLE
Common concentration examples.
| Vial Mass | Diluent | Concentration | Example Aliquot | Required Volume |
|---|---|---|---|---|
| 5 mg | 1 mL | 5,000 mcg/mL | 250 mcg | 0.050 mL |
| 5 mg | 2 mL | 2,500 mcg/mL | 250 mcg | 0.100 mL |
| 10 mg | 2 mL | 5,000 mcg/mL | 250 mcg | 0.050 mL |
| 10 mg | 3 mL | 3,333 mcg/mL | 250 mcg | 0.075 mL |
| 15 mg | 3 mL | 5,000 mcg/mL | 250 mcg | 0.050 mL |

05 / RESEARCH USE NOTICE
Built for laboratory reference. Not clinical guidance.

It is not intended to determine an appropriate dose, treatment protocol, route of administration or clinical use for humans or animals. Research materials should be handled according to applicable technical documentation, institutional procedures and local law.
06 / FREQUENTLY ASKED QUESTIONS
Calculator questions.
The total peptide mass in micrograms is divided by
the total liquid volume in millilitres to produce a
concentration expressed as mcg/mL.
No. Increasing liquid volume changes the concentration
of the solution but does not change the total mass of
material originally present in the vial.
One milligram equals 1,000 micrograms.
An aliquot is a measured portion taken from a larger
laboratory solution for a specific research procedure.
No. The calculator performs concentration and volume
mathematics only and does not provide dosing recommendations.
No. This tool is presented solely as a laboratory
research reference.
